Objectives: The purpose of this study is to analyze the relationship between dual smoking and mental health. Methods: This study was conducted on 5,879 Korean adults, and a logistic regression analysis was conducted to investigate the relationship between smoking type and mental health. Results: The types of smoking were surveyed as 'dual smoking' 6.1%, 'electronic cigarette' 1.7%, 'general smoking' 12.1%, and 'non-smoking' 80.1%.. The risk of diagnosing depression in the dual smoking group was 2.87 times higher than in the non-smoking group, the risk of depression was 1.66 times higher than in the non-smoking group, and the risk of stress was 1.62 times higher. Conclusion: Even in adulthood, health education such as smoking prevention education and smoking cessation education should be conducted.

Background and objectives: One-person households are the fastest growing family type in Korea. They bring social concerns such as weakened social integration, increasing poverty and social isolation. They are not homogeneous but heterogeneous groups depending on their socio-demographic characteristics including generation. This study compared the life satisfaction level as well as factors affecting it among the three one-person household generations Methods: The 13th wave of the Korea Welfare Panel dataset with 1,187 respondents was utilized. For data analysis Chi-square test, analysis of variance and hierarchical regression analysis were employed. Generations are divided into three, namely young adult (20-39), the middle-aged (40-64) and the elderly (65 and over). Result: The life satisfaction level was highest among the young adult one-person household generation, followed by the middle-aged and the elderly generation. The common factors affecting life satisfaction of the three generations were physical as well as mental health, including self-esteem and depression. However, there were more factors different from generation to generation. As for the young adult, age, religion, and smoking were significant. As for the middle aged and the elderly, gender (male) and income were significant. Additionally, age, home-ownership and drinking were significant to the elderly generation. Conclusions: As there are differences as well as similarities among the three generations, policies for one-person households need to be devised considering these findings. For all generations, both physical and mental health policies are needed. For young adult strengthening social relations, providing decent jobs, and promoting anti-smoking policy are major agenda, and for the middle-aged and the elderly, assisting in social capital accumulation (for male), providing stable jobs and diverse leisure activities, and securing income. Additionally, for the elderly, expanding the social security system and housing support are needed.

Objectives: The purpose of this study is to analyze the research trends on oral health literacy in South Korea and to suggest the direction of future research, Methods: The literatures were searched using KISS, RISS, KMBASE, KoreaMed, Nanet and NDSL. A total of 17,433 documents were retrieved by database searching. The final 34 literatures that satisfied the inclusion criteria were selected for analyzing. A content analysis was performed on 34 literatures on the topics of oral health literacy which had been published from 2012 to 2019. Results: Most of the 34 literatures, 23 articles and 11 thesises were descriptive-correlation studies, but there was no intervention study. The participants studied in the selected literatures were mostly adults followed by elderly and other groups including foreigner. More troubling sufficient samples and sampling methods were lacking at the population level. The validation of the used health literacy instruments was not sufficient. Conclusions: The unification of translation terminology for oral health literacy and the standardized instrument to test oral health literacy are needed. And to improve the level of oral health literacy, studies should be conducted using various variables. It is also necessary to develop the oral health education programs that can improve the level of oral health literacy. In the future, meta-analysis on the oral health literacy are needed for cumulating findings and drawing more reliable and general conclusions.

서론: 청소년기는 여러 생물학적 변화 및 사고방식의 발전과 함께 성행위가 나타나기 시작하는 인간성장의 단계이다. 쿠바를 포함한 많은 라틴아메리카 국가들은 청소년들의 성관계 조기 시작과 같은 위험한 성행동을 보고해 왔다. 이 연구의 목적은 사회 인구 통계학적 요소, 정보 수단 및 쿠바의 십대 학생의 성적 행동에 영향을 미치는 행동 요소 사이의 관계를 확립하는 것이다. 방법: 본 연구를 위해 쿠바 십대들의 생식 및 성적 행동 경향 파악을 위해 설문조사를 실시했다. 전체 260명 중 성경험 여부에 응답한 232명에 대해 인구사회학적 특성의 파악과 성 관련 정보수집수단, 행동적 요인과 성행동 사이의 연관성분석을 위해 회귀분석을 실시했다. 결과: 대상자들의 평균 연령은 16.9세이고 대다수는 여성(64.2%)이었다. 232명 중에 45.3%는 무신론자, 31.2%는 유신론자이었다. 종교의 중요도에 대한 생각은 39.2%가 종교가 중요하지 않다고 응답했고 34.0%는 중요하다고, 14.0%는 종교가 매우 중요하다고 응답했다. 응답자 232명 중 80.5%의 십대들이 성관계 경험이 있다고 하였으며 첫 성관계 평균 연령은 14.65세였다. 피임약을 사용한 비율은 63.8%이었다. 인구사회학적 특성 중에 성별은 성관계와 통계적으로 유의미한 연관성을 나타냈으며, 남성은 여성보다 성관계를 가질 가능성이 3.8 배 더 높았다. 또한, 종교는 성관계와 관련이 없었다. 그러나 나이는 통계적으로 유의미한 것으로 나타났으며, 나이가 한 살 많아질수록 성관계 가능성은 2.29배 증가함을 알 수 있었다. 성 관련 정보수집수단과 관련하여 친구와 학교의 성교육 커리큘럼이 청소년들의 성행동을 결정하는 중요한 요인이었다. 결론: 쿠바 십대들의 연령과 성별은 성행동의 중요한 결정요인으로 나타났다. 또한, 쿠바의 십대들은 친구와 학교로부터 성에 대한 정보를 수집하고 있으므로 학교에서 보다 종합적인 성교육 프로그램을 만드는 등의 십대들의 성행동 문제를 다룰 때 영향요인들을 고려해야 할 것이다.
